2014-10-15Here we have the patch for gold aarch64 backend to support relaxation.Han Shen1-39/+38
In short relaxation is the linker's generation of stubs that fixes the out-of-range jumps/branches in the original object file. With this implementation, we are able to link a 456MB aarch64 application. Tested: 1) Build natively on x86_64 and aarch64 machines. 2) Pass unit tests regarding relaxation.
